Merge branch 'main' of ssh://ramanujan.glitch.university:2222/glitch-university/gupi-osint-board

A dialogue line can award an achievement when reached (granted server-side,
validated against the player's current node so it can't be forged) and an
option can require an achievement to be offered (filtered out of the resolved
tree otherwise). authorGraph gains a branching form (utterance key/parent/
terminal) so option trees — not just linear lines — can be seeded. This is
gaps 1 & 2 for the Barricelli Dobby/Glitch-Hunter dialogues; phone dialing
stays stubbed.

+
 ## Data and API
 
 The server stores its tables and migration ledger in the dedicated `osint` schema of PostgreSQL. `DATABASE_URL` is required.
 
 The accepted model stores each playable or editable level as an isolated mutable board of normalized exhibits. Immutable template-version boards are cloned to create levels, and mutable levels can be cloned back into new template versions. Assets remain immutable and reusable across those copies.
 
-The running POC still uses the earlier `widgets` and `playthrough_*` tables while the exhibit-schema cutover is prepared. They are explicitly transitional; new domain concepts should follow the exhibit model rather than extending those tables.
+The running POC uses the canonical exhibit schema directly. The earlier JSON case store, `widgets`, and `playthrough_*` tables were removed in migration 006.
 
 The API surface is:
 
 - `GET /api/levels`
 - `POST /api/levels` (editor only)
+- `GET /api/templates`
+- `POST /api/templates/:slug/levels` (instantiate a version; editor only)
 - `GET /api/levels/:id`
 - `PUT /api/levels/:id`
 - `POST /api/levels/:id/reset`
+- `POST /api/levels/:id/templates` (save a new immutable version; editor only)
+- `POST /api/levels/:id/documents` (player-uploaded evidence)
+- `POST /api/levels/:id/reveals/seen`
+- `GET /api/levels/:id/flags` (admin only)
+- `PUT /api/levels/:id/flags/:key` (admin only)
+- `DELETE /api/levels/:id/flags/:key` (admin only)
+- `GET /api/levels/:id/evidence-match-rules` (admin only)
+- `POST /api/levels/:id/evidence-match-rules` (editor only)
+- `PUT /api/levels/:id/evidence-match-rules/:ruleId` (editor only)
+- `DELETE /api/levels/:id/evidence-match-rules/:ruleId` (editor only)
+- `GET /api/assets/:id`
+- `GET /api/session` (verified session and admin capability summary)
 - `GET /api/health`
 
 The browser also keeps a local emergency copy so a network interruption does not lose an in-progress board.
 
 ## Level editor
 
-Set `LEVEL_EDITING_ENABLED=true` and open `/?edit=1`. If the database is empty, this surface creates the first blank level. The target model intentionally makes editing and playing the same operation against a mutable level; authoring additionally exposes “save as template”. The current playthrough overlay remains only until the exhibit-schema migration is complete.
+Set `LEVEL_EDITING_ENABLED=true` and open `/?edit=1` while signed in with a JWT carrying `role: "admin"`. The shared `auth_token` cookie is verified with `JWT_SECRET`; the legacy `isAdmin: true` claim remains compatible. If the database is empty, this surface creates the first blank level. Editing and playing are the same operation against a mutable level. Authoring actions live under the **Admin** menu. Saving a template creates a new immutable version; instantiating gives every exhibit a fresh ID while sharing immutable binary assets. Reset restores the exact template version from which a level was created.
 
-In edit mode, files can be dragged from the desktop onto the board or selected with **Import Document**. Images, PDFs, and text files render inside document windows; unknown formats remain downloadable source files. Extracted evidence becomes an editable folder widget. Its editor controls the title, annotation, contained documents, and each source document's publication time. The default upload limit is 25 MB and can be changed with `MAX_DOCUMENT_BYTES`.
+For the standalone development Compose stack, visit `/api/dev/admin-session?returnTo=/?edit=1` once to receive a local signed admin cookie. This helper does not exist in production.
 
-Production defaults editing to disabled. Set `LEVEL_EDITING_ENABLED=true` in `/opt/gu_common/.env.prod` only when the authoring surface should be available. This is a capability switch, not authentication; add authentication before exposing production editing to untrusted users.
+Files can be dragged from the desktop onto the board or selected with **Add Document**. Pasting a clipboard image creates a persisted image Document, which supports ordinary macOS and Windows screenshot workflows. Images, PDFs, and text files render inside document windows; unknown formats remain downloadable source files. Extracted evidence becomes an editable folder widget. Its editor controls the title, annotation, contained documents, and each source document's publication time. The default upload limit is 25 MB and can be changed with `MAX_DOCUMENT_BYTES`.
+
+Image uploads are OCRed by the Tesseract executable bundled into the application image; text-file uploads use their text directly. Extracted text is stored against the immutable asset, copied into the Document's searchable body, and evaluated against level-authored fuzzy passage rules. A successful rule awards its configured flag and immediately participates in ordinary document reveals. Rules, anchors, per-anchor scores, and evaluation provenance are normalized PostgreSQL data—no case text is compiled into the engine. OCR is time-limited and failure-tolerant: the source remains on the board even when text extraction fails. `OCR_LANGUAGES`, `OCR_TIMEOUT_MS`, `MAX_OCR_BYTES`, and `MAX_EXTRACTED_TEXT_CHARACTERS` tune the worker; `OCR_ENABLED=false` disables image OCR without disabling uploads. Authors configure passages under **Admin → Evidence Matching** while editing a level.
+
+In author mode, a Document may be assigned comma-separated reveal flags in its metadata editor. Play-mode level responses omit gated Documents until all requirements are earned. Admins can exercise the demo through **Admin → Level Flags**; newly delivered evidence receives a one-time arrival animation.
+
+Production defaults editing to disabled. Set `LEVEL_EDITING_ENABLED=true` in `/opt/gu_common/.env.prod` only when the authoring surface should be available. `JWT_SECRET` is inherited from that shared environment, and authoring endpoints additionally require a verified admin claim.
 
 ## POC exhibit and widget contract
 
@@ -64,19 +111,25 @@ The current POC defines four exhibit families and corresponding frontend widgets
 - **Folder** — a titled, annotated collection. Opening it expands its contained source files to their saved relation-bound board positions; closing it retracts and hides them.
 - **Source file** — immutable binary evidence plus user-editable title, publication time, file type, and arbitrary key/value metadata. Image is the first fully visual file renderer. PDF, web capture, email, article, filing, price list, text, and generic file are registered types with a generic fallback until their renderers are built.

+- **Event** — an investigator-authored “this happened” statement with narrative text, an occurrence time, and normalized links to supporting exhibits. The editor manages citations, dashed support lines keep them visually distinct from red investigative thread, and chronologically ordered events form the reconstructed-story strip.
 
-The planned **Party** family adds distinct Person and Organization exhibits (businesses are organizations). Their dossier-like widgets reveal normalized evidence associations, but parties remain identity objects rather than special folders.
+The **Party** family has distinct Person and Organization subtypes (businesses are organizations). Names begin as concepts in the level brief. The investigator classifies each concept, which creates the appropriate dossier exhibit and records the resolution. Expected classifications remain author-only. Dossiers store aliases and normalized evidence associations, but parties remain identity objects rather than special folders.
+
+**Red thread** is a normalized connection between any two exhibits, including expanded source documents. Each connection may carry an investigator-authored relation tag, a persisted tightness percentage, and a presentation choice. `LUGGAGE` reuses the investigator note's expressive hanging tag, rotating to read before opening the editor; `COMPACT` keeps the original knot-and-label treatment and opens the editor directly. Both remain available while the POC establishes which works best. When a connected source document is retracted into its folder, the visible endpoint follows it to the folder until it is expanded again.
 
 Folder ownership is stored as a normalized membership. The contained document exhibit owns its expanded `xpos` and `ypos`. For deterministic collapse behavior, one exhibit has at most one owning folder; two exhibits may reuse the same immutable asset when the same source file must appear in multiple folders.
 
 An open folder draws a pale red containment band to each expanded file. Each dated file independently projects a grey line to the temporal index. This allows the player to arrange files until those grey lines are vertical, close the folder, and later reopen the same arrangement.
 
-The frontend widget registry maps an exhibit type, and optionally a document type, to its React visualization. Widgets do not own investigation-domain data.
+The timeline uses an optional board-level start and end date. Click **Timeline** in the menu or the displayed range in the footer to adjust it; **Use Automatic Range** returns to evidence-derived bounds. Configured bounds are normalized board data and follow template cloning and reset. Evidence outside the visible interval remains available and is pinned to the nearest timeline edge.
+
+The typed frontend widget registry maps each exhibit type, and each document type, to its React visualization. Adding a domain type now produces a compile-time requirement to register its renderer. Widgets do not own investigation-domain data.
+
+On desktop, an ordinary mouse wheel or two-finger trackpad scroll zooms the board. Desktop pinch gestures are consumed so they cannot zoom both the browser and board. Touch devices use a two-finger pinch on the board; toolbar controls remain available on every device.

+## Milestone 5: claim-driven case report
+
+The purpose of this milestone is the gameplay loop, not a knowledge graph: a Claim is a pinned proposition, source exhibits connect to it with red thread, and each thread's luggage-tag text explains how that source supports the Claim. Those explanations become the evidence section of the Case Report.
+
+### 5.1 Lock the gameplay and temporal rules

+- [x] Treat a claim-to-document thread label as an evidentiary statement; new threads begin with `Proof that…`.
+- [x] Use the same persisted connection statement on the luggage tag and in the report.
+- [ ] Derive the Claim date from the earliest non-null temporal date of its two endpoint exhibits; never use `created_at` or the current time.
+- [ ] Use Event `occurred_at` and a Document's primary timeline date as direct endpoint dates. For a Folder, use the earliest dated contained Document. Leave a Claim undated when neither endpoint supplies a date.
+- [ ] Place undated Claims after dated Claims in the initial report order while keeping them fully editable and reorderable.
+- [ ] Treat the derived date as the initial chronological suggestion only. Manual report ordering must not rewrite exhibit or Claim dates.
+### 5.2 Add normalized persistence
+
+- [x] Add normalized `claim_exhibits` as an Exhibit subtype; Claims are not encoded as connection labels.
+- [ ] Move luggage-tag presentation fields out of `exhibit_connections`; retain evidentiary statement, curve tightness, and endpoints on the connection.
+- [x] Add one board-owned `case_report` plus immutable level-owned submissions and normalized submission issues.
+- [x] Assign stable, board-local display numbers to cite exhibits as `Exhibit 3` independently of board position, z-index, or report order.
+- [ ] Enforce same-board ownership for the Claim's connection, both endpoint exhibits, report, and report membership.
+- [ ] Delete a Claim and its report membership transactionally when its luggage tag is removed, while retaining the now-untagged thread.
+- [ ] Delete both the Claim and connection when the thread itself is removed.
+- [x] Clone board-owned Claims with fresh IDs during template creation and instantiation.
+- [x] Make reset discard player-created Claims/report submissions and restore exactly the source template report configuration.
+- [ ] Keep uploaded binary evidence in MinIO. Reports and Claims reference Document exhibits and asset metadata; they never duplicate or embed asset bytes.
+
+### 5.3 Expose a focused API contract
+
+- [ ] Add a typed Claim DTO to an investigative connection instead of exposing a free-form connection `label`.
+- [ ] Return each Claim's derived date and its two stable exhibit citations in the report response.
+- [ ] Add granular operations to create, edit, and remove a Claim without replacing the complete board state.
+- [ ] Add a report endpoint that returns ordered Claim rows and an atomic reorder operation.
+- [ ] Reject empty Claim text, invalid connection ownership, duplicate Claims on one connection, and report orders containing foreign or duplicate Claim IDs.
+- [ ] Protect Claim and report writes with the board revision so concurrent saves cannot silently overwrite reasoning.
+
+### 5.4 Turn luggage tags into Claim widgets
+
+- [ ] Change the thread prompt from “Add tag” to “Explain this connection,” with a secondary option to leave the thread untagged.
+- [ ] Create the Claim and its luggage-tag presentation in one interaction, preserving the current tightening animation.
+- [ ] Keep both `LUGGAGE` and `COMPACT` as visual presentations of the same Claim entity while playtesting them.
+- [ ] Preserve draggable percentage and tension-constrained lateral offset as Claim presentation state.
+- [ ] Rename tag-oriented frontend types and commands to Claim terminology without changing the established visual design.
+- [ ] Give a newly created Claim a subtle “added to report” ink animation or badge without interrupting board work.
+
+### 5.5 Build the typewriter case report
+The end goal is that a case report is prepopulated by the claims the player made during the investigation so that a skeleon of the case solution is present. The player must simply edit the case report and submit it. 
+
+- [x] Add **Case Report** as a primary menu item and implement its first persistent report surface, separate from exhibits and the timeline.
+- [ ] Provide an empty state that explains that explaining red threads will create the report, without revealing a solution or forcing a tutorial.
+- [ ] Initially arrange Claim rows chronologically by derived date, using the order parameters on the claim as tie-breaker and undated Claims last, below a horizontal rule that says (missing date)
+- [x] Render the Scene 7 Claim with typewritten, stable Exhibit citations and editable date/source provenance.
+- [ ] It needs to be possible to add free text before and after the claims. Coloured inline text (use span elements)  have a specific class and id can be edited
+- [ ] -Make Claim text editable inline. Persist through the Claim API so the luggage tag updates immediately.
+- [ ] Support pointer and keyboard reordering of Claim rows and persist the resulting explicit report order into order column of the claim. 
+- [ ] Clicking a Claim must minimize the report as appropriate, center its thread, and briefly illuminate the curve and luggage tag.
+- [ ] Clicking an exhibit citation must locate and highlight that exhibit using the existing tray/board locator treatment.
+- [x] Ensure the first Case Report surface is legible and operable on portrait mobile layouts as well as desktop.
+- [ ] Add restrained typewriter, paper, and ink feedback while respecting reduced-motion preferences.
+
+### 5.6 Test the reasoning loop
+
+- [ ] Unit-test endpoint date resolution for Event, Document, Folder, partially dated, fully undated, and invalid-date cases.
+- [ ] Migration-test the one-Claim-per-thread constraint, cascading behavior, same-board enforcement, and report ordering constraints.
+- [ ] Integration-test create/edit/remove Claim, two-way text synchronization, report reorder, reload persistence, reset, and template cloning.
+- [ ] Verify that Claims citing uploaded Document exhibits survive cloning while their immutable assets remain shared through MinIO.
+- [ ] Add a browser test that creates several connections out of chronological order, explains them, opens the report, edits and reorders the Claims, then returns to each highlighted thread.
+- [ ] Play the Glass Harbor mystery using Claims as the primary reasoning mechanism and record whether the generated report makes the conclusion emerge naturally.
+- [ ] Revise prompts, animation, initial ordering, and report typography based on that playtest before adding automated evaluation.
+
+### 5.7 Deliberately deferred
+
+- [ ] Design a hidden, template-versioned solution rubric only after the deterministic Claim/report loop is enjoyable and dependable.
+- [ ] Add LLM report evaluation as a later milestone with structured citations, calibrated uncertainty, and reproducible evaluator output.
+- [ ] Do not add general-purpose semantic edge roles, Claim hubs, Claim-to-Claim links, or a knowledge-graph ontology as part of this milestone.
+
+### Milestone 5 definition of done
+A player can connect exhibits, explain each connection with a luggage-tag Claim, discover those exact words in a chronological typewriter report, improve and reorder the Claims, follow every citation back to the board, reload without loss, and reset safely to the template. No LLM is required for this experience to work.

+# Board demo scope
+
+The active demo starts directly on a mutable OSINT board. Campaign navigation,
+cutscenes, dialogue, NPC presentation, and story-graph progression are not part of
+this slice. Their existing code and migrations remain isolated for possible later
+work, but the board does not invoke them.
+
+## Included gameplay
+
+- A level loads its currently available normalized exhibits, board arrangement,
+  folders, threads, parties, events, and timeline.
+- A document may require one or more boolean level flags. Play-mode responses omit
+  an unavailable document and every relation or thread touching it. Author mode
+  exposes the requirements in the document metadata editor.
+- The first time an available document is delivered to a level, it receives a
+  short **NEW EVIDENCE** arrival animation. The acknowledgement is persisted so a
+  normal reload does not replay it.
+- Administrators can inspect, award, and revoke demo flags from **Admin → Level
+  Flags**. This is a test/authoring control; future gameplay systems may award the
+  same flags without changing the document-gating model.
+- Any player may add evidence by choosing a file, dragging a file onto the board,
+  or pasting an image from the clipboard. A pasted macOS or Windows screenshot is
+  uploaded to object storage and created as a normalized image Document near the
+  center of the current viewport.
+- Uploaded images are OCRed and uploaded text files are read directly. Extracted
+  text becomes searchable Document content and is compared with board-owned fuzzy
+  passage rules. Matching enough distinctive anchors awards the rule's flag; an
+  OCR error never rejects or removes the player's source.
+
+## Gate semantics
+
+Flags are lowercase keys such as `lead.auction_catalogue`. A document with no
+requirements is visible at level load. A document with several requirements is
+visible only after **all** of them have been earned. Flags belong to the mutable
+level; requirements belong to the board and therefore clone with template
+versions. The server is the visibility authority.
+
+Evidence recognition rules also belong to the board and clone with template
+versions. Each rule names a flag, contains one or more reference passages, gives
+each passage a similarity threshold, and states how many passages must match.
+Evaluation rows and their per-anchor scores belong to the mutable level, providing
+an audit trail for automatic victories and reveals.
+
+The bundled Glass Harbor manifest gates the auction catalogue behind
+`lead.auction_catalogue`, providing one small reveal for the demo.

+### Claim and report semantics
+
+A Claim is a pinned proposition the investigator is asked to establish, such as
+**“Nils Aall Barricelli was an inventor.”** It is an Exhibit subtype rather than
+text hidden in a widget or a connection. One Claim can therefore receive multiple
+supporting red threads without becoming a knowledge-graph hub.
+
+For a Claim-to-Document connection, the connection label is the evidentiary
+statement—initially `Proof that…`—and the Document supplies the source date,

+numbers live in `exhibit_citations`; they do not depend on z-order or position.
+
+`case_reports` holds clonable board configuration. Mutable, server-evaluated
+filings live in `case_report_submissions`, with individual deficiencies in
+`case_report_submission_issues`. A report can therefore record the useful state
+“evidence accepted, report incomplete” without weakening the evidence match or
+pretending the level has been fully accepted.
+
 ### Event semantics
 
 An event is an investigator-authored assertion: **“this happened.”** It is not source evidence and must not silently inherit a document's publication time.
 
 - `narrative_text` states what the investigator believes happened.
-- `occurred_at` places that assertion in reconstructed time.
+- Nullable `occurred_at` places that assertion in reconstructed time when known. It must never inherit the exhibit's creation timestamp.

+# First slice: splash → New Game → briefing → board
+
+Scope: the thinnest end-to-end narrative thread. A player lands on a
+**PRINCIPAL INVESTIGATOR** splash, clicks **New Game**, watches one scripted
+briefing cutscene from the Glitch University professor (with a pose swap), and
+arrives on the existing Glass Harbor board. Identity is a hard-coded test user.
+All cutscene content is authored through the manifest importer — nothing
+hard-coded in React.
+
+Explicitly **out of scope** for this slice: the admin authoring panel, multiple
+chapters, the debrief/back-to-board scenes, dialogue branching, and any LLM. The
+schema below only reserves those (`kind`, nullable `advances_to`) — it does not
+build them.
+
+## Ordered tasks
+
+### 1. Identity: hard-coded test user (do this first)
+- [ ] Add `resolveUserId(req)` to `server/auth.ts`: return `authClaims.sub` when
+  present, else a single fixed dev `TEST_USER_ID`. Leave `requireAdmin` and the
+  symmetric-secret admin path untouched.
+- [ ] Note in code that the external `glitch.university` key-exchange path
+  replaces only the fallback branch later; the `user_id` column does not change.
+
+### 2. Migration `015_narrative_layer.sql`
+Minimal tables to run one scripted scene against one chapter.
+- [ ] `mysteries (id, slug UNIQUE, title)` and `mystery_chapters (mystery_id,
+  chapter_index, level_template_version_id, PK (mystery_id, chapter_index))`.
+- [ ] `npcs (id, mystery_id, name, role, default_pose_key)`.
+- [ ] `poses (id, npc_id, pose_key, asset_id → osint.assets, UNIQUE (npc_id,
+  pose_key))`.
+- [ ] `cutscenes (id, mystery_id, chapter_index NULLABLE, slot, title)`.
+- [ ] `dialogue_steps (id, cutscene_id, step_key, sort_order, npc_id, pose_key,
+  kind DEFAULT 'scripted', text, advances_to NULLABLE, UNIQUE (cutscene_id,
+  sort_order))`.
+- [ ] `playthroughs (id, user_id, mystery_id, current_chapter_index,
+  current_level_id, created_at)`.
+- [ ] `seen_dialogue (playthrough_id, cutscene_id, seen_at, PK (playthrough_id,
+  cutscene_id))`. (Cutscene-level for the slice; step-level deferred.)
+
+### 3. Repository (`server/narrativeRepository.ts`, or extend levelRepository)
+- [ ] `createPlaythrough(userId, mysterySlug)`: instantiate chapter 1's template
+  version into a fresh level (reuse `instantiate_template_version`), insert the
+  playthrough, return it.
+- [ ] `getCurrentPlaythrough(userId)`: newest unfinished playthrough for the user.
+- [ ] `getPendingCutscene(playthrough)`: earliest unseen cutscene matching the
+  current slot/chapter, with steps joined to NPC + resolved pose asset URL.
+- [ ] `resolvePose(npc, poseKey)`: pure, unit-testable — requested `pose_key` →
+  NPC `default_pose_key` → `null` (no artwork). Return the asset URL or null.
+- [ ] `markCutsceneSeen(playthroughId, cutsceneId)`: idempotent insert.
+
+### 4. API (`server/index.ts`), all scoped to `resolveUserId(req)`
+- [ ] `POST /api/playthroughs` → create for the user, returns playthrough +
+  `pendingCutscene` + current level id.
+- [ ] `GET /api/playthroughs/current` → the user's playthrough or 204/empty.
+- [ ] `POST /api/playthroughs/:id/cutscenes/:cutsceneId/seen` → idempotent; 403 if
+  the playthrough's `user_id` is not the caller.
+
+### 5. Manifest importer (content path)
+- [ ] Extend `MysteryManifest` in `scripts/importMysteryTemplate.ts` with `cast[]`
+  (NPCs, each with `defaultPose` and `poses: { pose_key → asset path }`) and
+  `cutscenes[]` (`{ slot, chapter?, steps: [{ npc, pose, text }] }`).
+- [ ] Freeze a `mysteries` row + one `mystery_chapters` entry pointing at the
+  Glass Harbor template version, plus the cast and the intro cutscene, through the
+  same authenticated operations already used for assets.
+- [ ] Tolerate a cast with **no pose images** (author an NPC with just a name/role
+  so the slice runs art-free); upload images only if the manifest provides them.
+- [ ] Add a `mystery_intro` cutscene to `mysteries/glass-harbor/mystery.json`: the
+  professor briefing, 3–5 scripted steps, referencing pose keys that may not exist
+  yet (fallback handles it).
+
+### 6. Frontend
+- [ ] `SplashScreen`: title **PRINCIPAL INVESTIGATOR** over "Glitch University" in
+  the existing boot aesthetic; **New Game** always, **Resume** when `current`
+  returns a playthrough.
+- [ ] `DialogueOverlay`: render `pendingCutscene` steps; portrait from the
+  resolved pose (fallback to name+text when null); advance on click/Space/Enter;
+  typewriter with instant-reveal on first press; `prefers-reduced-motion`
+  respected; on finish call `…/seen` then reveal the board.
+- [ ] App boot: `GET …/current` → no playthrough shows splash; New Game POSTs,
+  loads the returned level (reuse existing level fetch/render), and plays
+  `pendingCutscene` before handing control to the board.
+
+### 7. Tests
+- [ ] Unit: `resolvePose` across requested / default / none; `getPendingCutscene`
+  returns only unseen scenes.
+- [ ] Integration: New Game creates a playthrough bound to the test user;
+  `current` returns it; `seen` is idempotent; a second user id cannot read or mark
+  the first user's playthrough.
+- [ ] Integration: importing the extended manifest freezes the NPC + intro
+  cutscene, and a New Game surfaces exactly those steps.
+- [ ] (Optional) Browser smoke: splash → New Game → overlay appears and advances →
+  board visible; reload does not replay the seen briefing.
+
+## Definition of done (slice)
+Against the test user, New Game creates a playthrough, the professor's scripted
+briefing plays with a pose swap (or clean name+text when art is absent), the Glass
+Harbor board loads, and a reload resumes without replaying the briefing — with the
+cutscene authored via the manifest, not hard-coded.
+
+## Open defaults (flag before coding if you disagree)
+- Second New Game **resumes** an unfinished playthrough (explicit Restart), rather
+  than always starting fresh.
+- `seen_dialogue` is **cutscene-level**, not step-level (no mid-scene resume yet).
+- One migration `015` holds all slice tables rather than several.

+# Narrative layer: campaigns, NPC cutscenes, and authoring
+
+This roadmap covers the narrative layer end to end: the **campaign** that chains
+levels into a mystery, the **NPCs / poses / cutscenes** the player watches
+between levels, and the **admin authoring panel** that lets a game designer build
+all of it in-app. Work generally proceeds top to bottom.
+
+**Design intent.** These mysteries are real-world scam cases that must actually be
+investigated to be understood. Such cases cannot be simplified, they 
+can only be staged for didactic discovery into levels.
+
+The LLM is not a decoration on the cutscenes — it
+is a **cognitive shim**: the assistant that keeps a player oriented as case
+complexity grows. A player can use this feature many times, but some very bright
+players might get it right on the first go. 
+This is what lets a mystery be as intricate as the real case
+demands without the player getting lost. The scripted narrative layer below is the
+delivery channel and the fallback; the LLM is the layer that scales comprehension.
+Section 9 is deferred in build order but primary in intent, so the model is shaped
+now to accommodate it (the `generated` step kind, the read-only context contract,
+and the authored case model).
+
+## Working agreement
+
+- All narrative content — campaigns, NPCs, poses, cutscenes, dialogue text — is
+  authored template data frozen through supported operations. None of it is
+  hard-coded into React components or SQL seed literals. The exception to this rule is 
+  custom cutscenes (react components) which are registered as components and referenced by the node.
+- The admin panel is a GUI over the **same** operations available to the manifest
+  importer; both paths freeze the same immutable template data.
+- A cutscene never mutates a board. The professor's scene *narrates* the new
+  document and goal; those exhibits and the updated brief already live in the
+  next chapter's template.
+- A narrative behavior is complete only when its PostgreSQL representation, API
+  behavior, frontend presentation, persistence, and focused tests agree.
+- Pose portraits are immutable shared bytes, stored and cloned exactly like
+  document image assets (MinIO + `objectStorage`); scenes reference assets, they
+  never duplicate them.
+
+## First vertical slice: "The Glass Harbour Diversion"
+
+Build the smallest end-to-end narrative loop before generalizing. Ship these in
+order; each is playable on its own.
+
+- [ ] Add the **splash screen** — "PRINCIPAL INVESTIGATOR", Glitch University —
+  with a single **New Game** action that creates a playthrough and launches the
+  first scene (sections 1, 6, 7).
+- [ ] Create a mystery named **The Glass Harbour Diversion** as a one-chapter
+  campaign wrapping the existing Glass Harbor level template (sections 1–2).
+- [ ] Add a **briefing NPC** (the Glitch University professor) and a
+  `mystery_intro` cutscene that briefs the player, using at least two poses to
+  prove pose-per-utterance (sections 2–3, 7).
+- [ ] Wire the briefing to play once on load and mark itself seen, then reveal the
+  first level's board (sections 1, 6, 7).
+- [ ] Author **two `level_debrief` end-scenes** the player reaches by reporting
+  back: one that **sends them back to the board** and one that **concludes the
+  mystery**. Model these as two end-of-scene outcomes (buttons), not branching.
+- [ ] Leave the back-to-board scene as **scripted** for now, but author it as a
+  `generated`-ready step (section 9) so the professor's hint can later be produced
+  from the player's Case Report explanation.
+
+## 1. Campaign / progression backbone
+
+- [ ] Define a **cutscene** node as something a) references a custom react component. 
+  That react can use potential **utterances** such that for example, it can play 
+  an ordered sequence utterance that brief the player: `(speaker NPC, pose, text)`. 
+  A node can be marked has_utterances which permits the admin user to add utterances in order.
+  [ ] A dialogue is another type of node that invokes the standard NPC dialogue component. This
+  has utterances, and consist of a graph where utterances either are spoken by the NPC or available for selection.
+  Example :  if the NPC utters "Are you ready?" this has two child utterances marked "player" which could be "yes" and no. The user may select these. "No" could in principle point back to the same utterance and "yes" to the next. If an utterance has a non NULL terminal id, then the game advances to the node pointed to by that terminal. Available terminals are only those who have the current dialogue node as it parent.
+- [ ] There exists "det_gate" nodes and "llm_gate" nodes. We begin with the deterministic gate only. The end result of a level is sent to a "det_gate". The det gate can inspect the output of the level and determine if the story should advance through one of its terminals. For now, the det-gate always returns the happy path terminal leading to the mystery being solved.
+
+## 2. NPC and pose catalog
+
+- [ ] Add an **NPC** entity (display name, short role e.g. "Glitch University
+  professor", default pose) owned by the mystery/template family, so casts are
+  authored rather than global magic strings.
+- [ ] Add **poses** as named portrait variants of an NPC (`pose_key` such as
+  `neutral`, `concerned`, `wry`, `pointing`), each backed by one immutable image
+  asset via the existing `assets` table + MinIO path.
+- [ ] Clone NPCs and pose→asset references (asset bytes reused, not copied) during
+  template freeze and instantiation, mirroring document image cloning.
+- [ ] Enforce that every dialogue step names an NPC that exists in the mystery's
+  cast; a **missing pose is never an error**.
+- [ ] Resolve a step's portrait at render time with graceful fallback: the
+  requested `pose_key`, else the NPC's **`default`** pose, else **no artwork**
+  (speaker name + text only). This lets authors add poses incrementally and keeps
+  the first slice playable with zero uploaded art.
+
+## 6. API contract
+
+- [ ] **New Game / session:** add `POST …/playthroughs` (create for the current
+  `user_id`, per section 1) and `GET …/playthroughs/current` so the splash can
+  offer New Game or Resume; scope every playthrough read/write to the caller's
+  `user_id` so one player cannot touch another's game state.
+- [ ] **Play mode:** return a compact `pendingCutscene` payload (slot, ordered
+  steps with resolved NPC name + pose asset URL) when one is due and unseen; add
+  `POST …/playthroughs/:id/cutscenes/:cutsceneId/seen` (idempotent) and
+  `POST …/playthroughs/:id/advance` implementing section 1's transactional advance.
+- [ ] **Admin mode:** add authenticated CRUD for mysteries, chapter ordering,
+  NPCs and poses, and dialogue scenes/steps, plus the campaign freeze operation —
+  all behind the existing admin JWT and `edit=1` gate.
+- [ ] Keep authoring-only fields (raw pose keys, expected-solution data, unfrozen
+  drafts) out of play-mode responses, consistent with how brief concept
+  `expectedPartyKind` is already hidden in play mode.
+
+
+## Definition of done
+
+A game designer can, in the admin panel, create a mystery, select existing levels
+as ordered chapters, create NPCs and upload named poses, craft dialogue scenes
+choosing a pose per step, and attach those scenes to chapter slots — then freeze
+it. A player lands on the "PRINCIPAL INVESTIGATOR" splash, chooses New Game to
+create a playthrough bound to their identity, watches the professor speak
+line-by-line with a
+changing portrait, investigates each board, reports back to advance a chapter that
+introduces a new document and goal, and reloads at any point without replaying
+seen scenes — with no dialogue text hard-coded in React and no cutscene mutating a
+board.

+# Persistent boards, gated exhibits, and citation codes
+
+Status: **demo subset implemented**. Migration 025 implements level-local boolean
+flags, normalized Document requirements, server-side filtering, persisted reveal
+acknowledgements, and the arrival animation. Board-key reuse, narrative-triggered
+live reveals, citation groups, and per-user playthrough overlays remain deferred.
+The broader design extends the story flow graph
+([story-graph.md](story-graph.md)) and the narrative layer
+([narrative-todo.md](narrative-todo.md)); interlocks with the Claim/Case Report
+work in [TODO.md](TODO.md) Milestone 5. Depends on the **flags / case-state**
+primitive (a per-playthrough key→value store) that the gates and dialogue effects
+also read and write.
+
+## Why
+
+A mystery is broken into short pieces so we can **meter how much evidence the
+player carries at once**. Interruptions — a phone call, a knock, a revealed note —
+should not throw the player off the board they are working on. So a single
+investigation scene is a **persistent, player-mutated board** that several graph
+nodes return to, and new evidence **arrives into that same board** when the story
+warrants it rather than being dumped up front or split across duplicated templates.
+
+Two capabilities, independent and both wanted:
+
+1. **A board that survives across nodes** — `[board] → [phone call] → [same board]`
+   returns the player to their exact arrangement and connections.
+2. **Flag-gated exhibits inside that board**, revealed with a diegetic "it arrived"
+   moment (reuses the existing document locator beam).
+
+## Board identity and reuse
+
+An authored level node **cannot** reference a clone id — the clone is created per
+playthrough at runtime. Instead:
+
+- A **level node** references a `level_template_version_id` **plus a `board_key`**
+  (a logical board slot, e.g. `"harbor-desk"`). `board_key` defaults to the
+  template if the author doesn't care about sharing.
+- A **playthrough** holds a map `board_key → level_id` (the mutable clone).
+- Entering a level node:
+  - if the playthrough already has a clone for that `board_key` → **reuse it**
+    (the player's mutated board, arrangement and connections intact);
+  - otherwise → **clone the template** and record `board_key → new level_id`.
+
+`board_key` is the thing that makes two nodes share a board. Two nodes on the same
+template with **different** keys get **separate** boards.
+
+## Gated exhibits
+
+- Every exhibit is **cloned in**, including gated ones; a gated exhibit carries a
+  **`reveal` condition over flags**. The player's saved board already contains the
+  note — it is simply inert until the flag flips.
+- **Visibility is computed server-side at load.** Given the playthrough's flags,
+  the play-mode payload includes only exhibits whose `reveal` condition is met;
+  hidden exhibits are stripped from the response (same discipline that already
+  hides authoring-only fields like `expectedPartyKind`). Players cannot peek
+  unrevealed evidence in the API.
+- **Gate the edges too.** Any `exhibit_connection` or event link whose endpoint is
+  a not-yet-revealed exhibit is hidden until that exhibit appears, so there are no
+  dangling references.
+
+## The arrival reveal
+
+- The board's effective content can change **while the player is standing on it** —
+  the phone is an always-available surface, so a call can set a flag mid-scene. So
+  reveal is **not load-only**: after any phone/dialogue interaction that sets flags,
+  re-evaluate board visibility and reveal live (the phone overlay refetches
+  visibility on hang-up).
+- Track a per-playthrough **`revealed-seen` set**. On (re)load or after an
+  interaction, any exhibit now visible but not yet in the set → play the arrival
+  animation (a sibling/reuse of the **document locator beam**), then add it to the
+  set. The flourish fires **once**, not on every reload.
+
+## Reset and New Game
+
+- **Reset = tidy the desk back to the delivered state.** Authored exhibits return
+  to their arrival positions and folders; the player's rearrangement is undone.
+  **Flags are untouched**, so anything a flag has already revealed is still
+  "arrived" and is restored at its authored position.
+- **New Game** re-clones the whole tree and is therefore the only thing that
+  **resets flags** and returns gated exhibits to hidden.
+
+**Open decision — player notes on reset.** Milestone 5's rule is "reset discards
+player-created claims." Current lean: reset also removes player-created exhibits
+(it restores the *delivered* state), and New Game is the only wipe of flags. The
+alternative is a gentler reset that re-files arrived exhibits but leaves the
+player's own notes in place. Settle before implementing.
+
+## Exhibit citation codes (A / B / M)
+
+A single running number breaks when players create many note exhibits, so codes
+live in fixed namespaces:
+
+- **Authored exhibits: group letter + index** — `A1, A2, …` for the initial
+  dossier, `B1, B2, …` for a batch that arrives later via a flag reveal, etc.
+  **The letter is the arrival group**, which ties straight into gated reveal: "new
+  evidence arrived" *is* the B-series lighting up. Indices are assigned **within
+  each group at freeze time** and frozen in the template, so authored codes never
+  shift, no matter what the player does.
+- **Player-created exhibits: a running `M` (miscellaneous) series** — `M1, M2,
+  M3…` in creation order, in their own namespace so player note-making cannot
+  disturb authored codes. M-numbering is per-level-instance and (given the reset
+  lean above) restarts only when player notes are cleared.
+- The author chooses an exhibit's **group**; the system owns the **numbering**.
+
+These codes are the **citation token everywhere** — board, luggage-tag Claims, the
+Case Report, and the LLM gate.
+
+## LLM gate contract
+
+- A gate can be **scripted to require specific authored codes** — e.g. "the report
+  must cite `A1` and `B2`, connected." That authored requirement list is the
+  deterministic backbone *under* the LLM, per the section-9 intent of scripting the
+  cognitive shim rather than trusting it blind.
+- If the player types the full report freehand, they must include the Exhibit codes;
+  the gate checks the required codes are present (and, later, that the reasoning
+  holds).
+
+## Relationship to fresh templates
+
+This **complements**, not replaces, new templates:
+
+- **Shared `board_key`** — interruptions *within* one investigation scene (calls, a
+  knock, a revealed note). Cleanly subsumes the earlier "note appears on the next
+  level" idea: the note is a gated exhibit on the *same* board that reveals after
+  the call.
+- **A fresh template** — the player genuinely moves to a new location/chapter with a
+  different board.
+
+## Implemented vs deferred
+
+Nothing here is built yet. New plumbing, smallest-first:
+
+1. **Flags** — the per-playthrough key→value store (shared with gates/dialogue).
+2. **`board_key` reuse** in level traversal + the playthrough `board_key → level_id`
+   map (clone-or-reuse).
+3. **`reveal` conditions on exhibits** + server-side play-mode visibility filtering
+   (exhibits and their edges).
+4. **`revealed-seen` set** + the arrival animation (locator-beam sibling), live
+   after flag changes.
+5. **A / B / M citation codes** — authored group + frozen index, player M-series;
+   surfaced on the board and threaded into Claims/report/LLM gate.
+
+Reset (desk-restore, flags-persist) and New Game (full re-clone) semantics as above.

+# Routes & how to test (dev)
+
+The front end picks what to render from the URL (see `src/main.tsx`). Vite dev
+server runs on `http://localhost:5173`.
+
+| URL | Renders | For |
+|---|---|---|
+| `/` | Splash → campaign (walks the story graph: cutscene → dialogue → hands off to the board) | Narrative / player flow |
+| `/node/<nodeId>` | **Dev/admin teleport** to a story node; a *level* node lands you on that level's board clone | Jumping around the tree while testing |
+| `/level/<levelId>` | A level board directly (add `?edit=1` to author) | Board work / editing |
+| `/admin` | Admin panel (mysteries, NPCs, assets, graph editor) | Authoring |
+| `/?phone=1` | 3D clamshell phone dialer spike | Phone prototype |
+
+## Game state (demo)
+
+A player's whole state is two things on their **playthrough**:
+- `playthroughs.current_node_id` — *where* they are (which node; a level node also has `current_level_id`, the board clone).
+- `achievements` — *what* they've earned (`(playthrough_id, flag_key, awarded_by_node_id)`).
+
+Normal play resolves position via `GET /api/playthroughs/current`. `/node/:id`
+is just the dev override that *writes* `current_node_id` (the `goto` teleport).
+
+## Quick test recipes
+
+**Play the campaign:** open `/` → New Game → click through the intro/briefing → you land on the board.
+
+**Jump straight to a node:** `/node/<id>`. List the current node ids:
+```bash
+docker exec osint-board-db psql postgres://osint:osint_secret@localhost:5432/osint_dev -At -F' | ' \
+  -c "SELECT n.id,n.node_type,n.label FROM osint.story_nodes n JOIN osint.mysteries m ON m.id=n.mystery_id WHERE m.slug='glass-harbor' ORDER BY n.ypos;"
+```
+(The `level` row is the board.)
+
+**Phone seam (achievements):** `/?phone=1` → dial `55501` (Elias) → voicemail → click **grant elias_number_callable** → the handset glows → dial `55501` again → connects. Voss `55502` stays voicemail; other numbers = unobtainable.
+
+**Reset to a clean slate:** `docker exec osint-board-db psql postgres://osint:osint_secret@localhost:5432/osint_dev -c "TRUNCATE osint.playthroughs CASCADE;"` then reload (playthroughs + achievements are wiped; `/` shows the splash again).
+
+## Dev-only endpoints
+
+Both are gated to `NODE_ENV !== 'production'` (swap for the admin JWT when we want them in a deployed build):
+- `POST /api/playthroughs/:id/goto` `{ nodeId }` — teleport (powers `/node/:id`).
+- `POST /api/playthroughs/:id/achievements` `{ flagKey }` — grant an achievement (stand-in until the server-side rule engine fires them from play). `GET` the same path lists earned achievements.
+
+Backend changes need a container rebuild: `docker compose -f docker-compose.dev.yml up -d --build app`. The Vite front end is live on 5173.

+Scene 7 teaches one idea: a screenshot found during an OSINT search can become

+The player opens an otherwise minimal OSINT board, reads the assignment
+**“Demonstrate OSINT skill: prove Nils Aall Barricelli was an inventor,”** finds

+the level. A URL and a written report are not required.
+

+                 -> Scene 7 complete -> continue to Scene 8
+=======
+Scene 7 teaches two linked ideas: a screenshot found during an OSINT search can
+become source evidence, and a finding is only as useful as the report that cites
+and explains that evidence.
+
+The player opens a minimal OSINT board, reads **“Demonstrate OSINT skill: prove
+Nils Aall Barricelli was an inventor,”** finds the relevant Google Patents result,
+and pastes or uploads one screenshot. The board creates a document, extracts its
+text, and recognizes the source. The player connects that document to the authored
+Claim, completes the evidentiary statement, and files the generated Case Report.
+
+```text
+paste screenshot -> document appears -> source is verified -> connect to Claim
+                 -> submit thin report -> provenance feedback -> accepted -> Scene 8
+
+## Product decisions
+
+These are decisions for this slice, not open design questions:
+
+- One suitable Google Patents screenshot is sufficient evidence.
+- Pasting and file upload are equivalent inputs and use the same server path.
+- The uploaded image and extracted text are retained as a real document on the
+  player's level.
+- The known patent source is recognized with deterministic OCR/fuzzy matching.
+  This is the fast, cheap, reproducible victory path.
+- A small LLM judge is a semantic fallback for other credible evidence and for
+  distinguishing Nils from his father. It must not overrule a trusted known-source
+  match.
+- The player does not have to provide a URL when the screenshot text itself
+  establishes provenance.
+- Evidence about Barricelli's father may unlock an optional discovery, but it
+  must not clear the assignment unless the evidence also supports the claim
+  about **Nils Aall Barricelli**.
+- The boarding-house fire article belongs to the later age/rescue assignment,
+  not to Scene 7's inventor victory condition.
+- Scene 7 records completion; Scene 8 owns the merit ceremony and awards
+  `barricelli_luggage`.
+- A failed or inconclusive evaluation never deletes the uploaded document and
+  never penalizes the player.
+
+## Existing foundation — reuse it
+
+Do not build a second upload, OCR, flag, or story system for this scene.
+
+- Migration `025_level_document_flags.sql` provides clonable document gates,
+  level flags, and reveal state.
+- Migration `026_achievements.sql` provides playthrough achievements.
+- Migration `027_evidence_text_matching.sql` provides immutable asset text
+  extractions, board-owned match rules/anchors, level-owned evaluations, and
+  auditable flag awards.
+- `server/ocr.ts` extracts plain text and runs Tesseract for images.
+- `server/evidenceMatching.ts` implements normalized fuzzy anchor matching.
+- `POST /api/levels/:id/documents` already persists the document, OCR result,
+  deterministic evaluations, and newly awarded level flags.
+- Screenshot paste already routes through document upload in the board UI.
+- The story graph already has level nodes and playthroughs with
+  `current_node_id` and `current_level_id`.
+
+The deterministic matcher has already handled noisy historic OCR, including a
+hyphenated `Bar- ricelli`, at useful confidence. Scene 7 should add authored
+patent anchors and a completion contract, not replace that matcher.
+
+## Proposed flags and identifiers
+
+Keep all identifiers authored in template data; these names are the recommended
+contract between independently developed branches.
+
+| Purpose | Key |
+|---|---|
+| Level goal | `barricelli.inventor-proof` |
+| Scene 7 completion flag | `scene7.nils_inventor_proved` |
+| Optional father discovery | `scene7.father_inventor_discovered` |
+| Scene 8 reward | `barricelli_luggage` |
+
+The first three are Scene 7 state. The last is a playthrough achievement awarded
+by Scene 8, never by the document upload endpoint.
+
+## Architecture
+
+### 1. Separate recognition from completion
+
+Recognition answers **“what does this document support?”** Completion answers
+**“are this level's authored requirements now satisfied?”** Do not hide level
+completion in a React conditional or special-case `Barricelli` in server code.
+
+Add a small, generic, board-owned goal model in the next migration (currently
+expected to be `028`; verify the migration number immediately before creating
+it):
+
+- `level_goals`
+  - belongs to a board and clones with a template;
+  - has a stable `goal_key`, player-facing title/instructions, enabled state, and
+    optional completion message;
+  - uses the existing `origin_*` pattern for cloned authoring objects.
+- `level_goal_flag_requirements`
+  - maps a goal to one or more required level `flag_key` values;
+  - Scene 7 has one requirement: `scene7.nils_inventor_proved`;
+  - all requirements are required for the first implementation. Add `any/all`
+    policy only when a real authored level needs it.
+
+Goal state is derived from level flags; do not add a second mutable `completed`
+boolean that can drift out of sync. If completion needs a timestamp, record a
+single idempotent goal-completion event with provenance.
+
+### 2. Known-source fast path
+
+Author one enabled `evidence_match_rule` on the Scene 7 template board. Its
+anchors should be distinctive passages visible in the actual Google Patents
+screenshot, such as a combination of patent number/title, inventor name, and
+invention language. Do not rely on the name alone.
+
+When enough anchors pass their authored thresholds, the existing evaluation
+awards `scene7.nils_inventor_proved`. The goal requirement consequently becomes
+satisfied in the same upload transaction.
+
+The reference OCR, anchor phrases, thresholds, canonical source metadata, and
+player-facing copy are template data. None belong in TypeScript constants or
+React branches. Expected/reference text must not be returned in play-mode API
+responses.
+
+### 3. Semantic fallback, not a free-form LLM gate
+
+Add a provider-independent `EvidenceJudge` interface in a new server module. It
+receives only allowlisted goal data and extracted OCR text and returns validated
+structured data, for example:
+
+```ts
+type EvidenceVerdict = {
+  subject: 'nils' | 'father' | 'ambiguous' | 'neither'
+  supportsInventorClaim: boolean
+=======
+- One suitable Google Patents screenshot is sufficient evidence, but not by itself
+  a complete investigation.
+- Clipboard paste and file upload use the same server path.
+- The image and OCR remain a real source document on the player's board.
+- A known-source fuzzy match is the fast, deterministic victory path.
+- A small semantic judge is a fallback for other credible sources and for
+  distinguishing Nils from his father. It cannot overrule the trusted path.
+- Evidence about Barricelli's father may award an optional discovery but does not
+  clear the assignment unless it also supports the claim about Nils.
+- The boarding-house fire belongs to the later age/rescue assignment, not Scene 7.
+- Scene 7 records `scene7.nils_inventor_proved`. Scene 8 owns the ceremony and
+  awards `barricelli_luggage`.
+- Inconclusive evaluation never deletes or penalizes uploaded evidence.
+- Scene 7 begins with one normalized, pinned Claim exhibit: **“Nils Aall
+  Barricelli was an inventor.”**
+- A new thread begins with **“Proof that…”**. This placeholder intentionally
+  produces a report that must be improved.
+- An accepted source connected to the Claim can earn a qualified pass while the
+  report is returned for missing date/source provenance.
+- The source link is encouraged but optional; date, source citation, investigator,
+  and a completed evidentiary statement are required.
+- Story advancement requires an accepted report when the template marks its report
+  as required.
+
+## Shared identifiers
+
+| Purpose | Key |
+|---|---|
+| Goal | `barricelli.inventor-proof` |
+| Scene 7 completion | `scene7.nils_inventor_proved` |
+| Optional father discovery | `scene7.father_inventor_discovered` |
+| Scene 8 reward | `barricelli_luggage` |
+
+All identifiers and content are template data. There must be no Barricelli
+conditional in React or server business logic.
+
+## Existing foundation
+
+- `025_level_document_flags.sql`: clonable document gates and level flags.
+- `026_achievements.sql`: playthrough achievements.
+- `027_evidence_text_matching.sql`: asset OCR, board match rules/anchors,
+  level-owned evaluations, and flag provenance.
+- `028_level_goals.sql`: board-owned goals and normalized flag requirements.
+- `029_semantic_evidence_judging.sql`: clonable semantic rules, level-owned
+  evaluations, and semantic flag provenance.
+- `030_evidence_match_source_metadata.sql`: author-only canonical source metadata.
+- `031_claim_case_reports.sql`: Claim exhibits, stable exhibit citations, report
+  configuration, immutable submissions, and normalized submission issues.
+- `server/ocr.ts`: plain-text extraction and Tesseract.
+- `server/evidenceMatching.ts`: OCR-tolerant fuzzy passage matching.
+- `POST /api/levels/:id/documents`: persistent upload plus OCR and matching.
+- The story runtime already tracks `current_node_id` and `current_level_id`.
+
+## Architecture contract
+
+### Recognition and completion are separate
+
+Recognition answers what a document supports. A goal answers whether the level's
+authored requirements have been satisfied. `level_goals` and
+`level_goal_flag_requirements` clone with a template. Goal completion is derived
+from level flags; there is no second mutable completion boolean.
+
+Play mode receives a goal's key, title, instructions, completion copy, status,
+and completion time. IDs, enabled state, required flags, target text, and judging
+prompts remain author-only.
+
+### Known-source fast path
+
+The Scene 7 template owns an `evidence_match_rule` with distinctive text visible
+in the real Google Patents result: a combination of patent number/title, inventor
+name, and invention language. A name alone is too generic. When enough anchors
+match, the existing matcher awards `scene7.nils_inventor_proved` in the upload
+transaction and the goal becomes complete immediately.
+
+Reference OCR, thresholds, source metadata, and copy live in the manifest/database,
+not TypeScript constants. The expected text is never returned to play mode.
+
+### Semantic fallback
+
+A provider-neutral `EvidenceJudge` receives only allowlisted goal data and OCR
+text. It returns strictly validated structured data:
+
+```ts
+type EvidenceVerdict = {
+  subject: 'target' | 'related' | 'ambiguous' | 'neither'
+  supportsClaim: boolean
+  evidenceExcerpt: string
+  confidence: number
+}
+```
+
+The provider/model name comes from environment configuration. Do not hard-code a
+Claude model identifier into level content or business logic. Treat OCR as
+untrusted quoted material: the prompt must explicitly ignore instructions found
+inside it, and the response must pass a strict schema before it can award a flag.
+
+Persist semantic rule configuration with the board and clone it with the
+template. Persist each evaluation against the level, document, extraction,
+rule/evaluator version, model/provider, verdict, excerpt, confidence, timestamps,
+and sanitized failure state. Add semantic-evaluation provenance to any level flag
+it awards. Never put provider credentials in PostgreSQL.
+
+Verdict routing for this scene:
+
+| Verdict | Result |
+|---|---|
+| Nils + inventor claim supported, high confidence | award `scene7.nils_inventor_proved` |
+| Father only + inventor claim supported | award `scene7.father_inventor_discovered`; do not complete |
+| Ambiguous, neither, unsupported, or below threshold | retain document; award nothing |
+| Provider unavailable/invalid response | retain document; mark evaluation retryable |
+
+Keep this evaluator narrower than the generic story-graph `llm_gate`. Scene 7 is
+judging a single uploaded source, not a report or arbitrary player state.
+
+### 4. Two-step server flow
+
+The primary Google Patents path remains synchronous and deterministic:
+
+1. Upload/paste persists the asset, document, OCR extraction, fuzzy evaluation,
+   flags, and current goal state in one transaction.
+2. If the trusted rule clears the goal, return success immediately and do not
+   spend an LLM call.
+3. If OCR succeeded but no trusted rule clears the goal, the client automatically
+   calls an idempotent semantic-judge endpoint for that document.
+4. The semantic endpoint uses a strict timeout, persists its result, and returns
+   refreshed goal state. A timeout is retryable and cannot roll back the upload.
+
+This avoids coupling document durability to an external provider without
+requiring a job queue for the demo. Make semantic evaluation idempotent for the
+same `(level, document, goal/rule, evaluator_version)`.
+
+### 5. Story progression contract
+
+Completing a board goal must be a server-authoritative transition:
+
+- verify that the JWT user owns the active playthrough;
+- verify that its `current_level_id` is the level being evaluated;
+- observe the derived completed goal;
+- idempotently record/promote `scene7.nils_inventor_proved` into the playthrough
+  state needed by the story runtime;
+- expose Scene 7's successful terminal so the player can continue to Scene 8.
+
+Do not let the browser award achievements through the current development-only
+achievement route. Do not make upload silently navigate before the player sees
+what was learned. Show the verification result, then expose a single **Continue**
+action (or a short authored transition that ends in the same action).
+
+The Scene 6 branch only needs to route its successful terminal to the Scene 7
+level node. The Scene 8 branch may depend on the completion state above and owns
+the `barricelli_luggage` award.
+
+## Work packages
+
+The packages are ordered for integration, but most implementation can happen on
+separate branches after the contracts above are agreed.
+
+### S7-A — Goal model and template cloning
+
+- [ ] Confirm the next free migration number; never edit applied migrations
+  `025`–`027`.
+- [ ] Add `level_goals` and `level_goal_flag_requirements` with board-scoped
+  foreign keys, uniqueness, indexes, and comments.
+- [ ] Extend template freeze/clone/instantiate so goals and requirements are
+  copied and retain origin provenance.
+- [ ] Derive `pending | complete` goal state from the level's current flags.
+- [ ] Add repository tests for cloning, isolation between two playthroughs, and
+  idempotent completion.
+- [ ] Keep the schema generic; there must be no Barricelli-specific column or
+  table.
+
+### S7-B — Scene content and deterministic recognition
+
+- [ ] Create/import the Scene 7 template and its brief as data.
+- [ ] Start the board without any solution-bearing document.
+- [ ] Obtain the exact target Google Patents screenshot used for acceptance and
+  run it through the local OCR service.
+- [ ] Author two or more distinctive match anchors from that extraction; avoid a
+  generic `Nils Barricelli`-only rule.
+- [ ] Tune thresholds against the target screenshot plus negative fixtures.
+- [ ] Configure the rule to award `scene7.nils_inventor_proved`.
+- [ ] Configure the goal requirement to consume that flag.
+- [ ] Store canonical patent/source metadata for administrators, while keeping a
+  pasted URL optional for players.
+- [ ] Add the content to the normal manifest/import path rather than SQL seed
+  literals or frontend code.
+
+### S7-C — Semantic judge
+
+- [ ] Add the provider-neutral `EvidenceJudge` interface and strict verdict
+  schema.
+- [ ] Add board-owned semantic rule configuration and level-owned evaluation
+  history with clone support and flag provenance.
+- [ ] Add environment variables for provider, model, timeout, maximum OCR
+  characters, and confidence threshold; document safe defaults in
+  `.env.example` without overwriting concurrent OCR configuration work.
+- [ ] Send extracted text, not raw image bytes, unless a later explicit design
+  requires a vision model.
+- [ ] Delimit and escape untrusted OCR content in the prompt.
+- [ ] Add an authenticated, ownership-checked, idempotent document-judge endpoint.
+- [ ] Award the completion or father-discovery flag only from validated persisted
+  verdicts.
+- [ ] Make timeouts, malformed responses, quota failures, and disabled provider
+  safe and retryable.
+- [ ] Do not log full evidence text or provider credentials.
+
+### S7-D — API and story bridge
+
+- [ ] Return compact goal state from the level response and document-upload
+  response: goal key, status, newly completed state, and player-facing message.
+- [ ] Never return reference anchors, expected text, private evaluator prompts,
+  or unpublished author data in play mode.
+- [ ] Add the semantic fallback endpoint/result to the typed client API.
+- [ ] Resolve the active playthrough for the level and enforce user ownership.
+- [ ] Promote completion server-side exactly once.
+- [ ] Make Scene 7's success terminal available only after the required goal is
+  complete.
+- [ ] Route that terminal to the Scene 8 node without implementing Scene 8's
+  ceremony in this branch.
+- [ ] Remove or fence the player-facing development route that can arbitrarily
+  grant achievements before production deployment.
+
+### S7-E — Board experience
+
+- [ ] Show the exact assignment prominently when Scene 7 opens.
+- [ ] Preserve both clipboard paste and drag/file upload; both call the same API.
+- [ ] Place the pasted screenshot as a new image document using the normal board
+  placement rules.
+- [ ] Show restrained stages such as **Saving source**, **Reading text**, and
+  **Checking evidence** without blocking board interaction unnecessarily.
+- [ ] On success, visually identify the accepted document and show:
+  **SOURCE VERIFIED — NILS AALL BARRICELLI: INVENTOR**.
+- [ ] After the player sees the result, expose one **Continue** action to Scene 8.
+- [ ] On father-only evidence, acknowledge the useful discovery and make clear
+  that evidence about Nils is still required.
+- [ ] On inconclusive evidence, keep the document and provide neutral guidance;
+  do not say that the player is wrong.
+- [ ] Respect reduced-motion settings and provide readable mobile feedback.
+- [ ] Do not introduce Scene 7 checks into generic exhibit components.
+
+### S7-F — Tests and acceptance fixtures
+
+- [ ] Add the actual Google Patents screenshot as a legally appropriate test
+  fixture, or store a compact derived OCR fixture if redistributing the image is
+  undesirable.
+- [ ] Unit-test OCR normalization and fuzzy matching for realistic line breaks,
+  punctuation, cropping, and name hyphenation.
+- [ ] Add negative fixtures: unrelated patent, father-only evidence, a generic
+  Barricelli biography, low-quality/empty OCR, and prompt-injection-like text.
+- [ ] Contract-test the semantic judge with a fake provider; CI must not call a
+  paid external model.
+- [ ] Integration-test target upload -> one document -> completion flag -> goal
+  complete, including a repeat upload/evaluation.
+- [ ] Integration-test father-only -> discovery flag -> goal still pending.
+- [ ] Integration-test provider failure -> document retained -> retry succeeds.
+- [ ] Integration-test two users/playthroughs so one player's evidence cannot
+  complete another player's level.
+- [ ] Browser-test clipboard paste through the success state and Continue action.
+- [ ] Run migrations against an empty database and an existing database at
+  migration `027`.
+- [ ] Run the full unit/integration suite, production build, and Docker smoke test.
+
+## API shape to converge on
+
+Exact route naming may follow the repository's conventions, but the frontend and
+backend branches should agree on a compact result like this before coding:
+
+```ts
+type LevelGoalState = {
+  key: string
+  title: string
+  status: 'pending' | 'complete'
+  newlyCompleted: boolean
+  message?: string
+}
+
+type DocumentAnalysis = {
+  extractionStatus: 'succeeded' | 'unsupported' | 'failed'
+  matchedFlags: string[]
+  awardedFlags: string[]
+  semanticStatus: 'not_needed' | 'available' | 'pending' | 'succeeded' | 'failed'
+  goals: LevelGoalState[]
+}

+
+## Security, privacy, and cost limits
+
+- Player endpoints require the same JWT identity and level ownership checks as
+  playthrough progression; admin authoring remains admin-only.
+- Limit upload bytes, OCR text sent to the model, model output tokens, request
+  duration, and retries.
+- Do not expose answer anchors or semantic judging instructions to the browser.
+- Do not trust filenames, MIME declarations, OCR text, or model output.
+- Use schema validation and a confidence threshold before mutating flags.
+- Store enough provenance to explain why a level cleared without retaining
+  unnecessary provider request/response payloads.
+- A deterministic trusted-source match saves cost and is authoritative. The LLM
+  is never called merely to reconfirm it.
+
+## Explicitly out of scope
+
+- Terminal game, Glitch University signup, Dobby, and Glitch Hunter scenes
+  (Scenes 1–6).
+- Scene 8's ceremony/3D luggage implementation and Scene 9's fire mystery.
+- A general knowledge graph, Case Report, claims, red-thread reasoning, or
+  multi-document synthesis.
+- Crawling the web, fetching a pasted URL, or validating a URL as a victory
+  requirement.
+- Training a custom OCR or language model.
+- Generalizing the story graph's future `llm_gate`; this slice may share a
+  provider adapter later, but does not depend on that larger feature.
+- Automatic rejection or deletion of irrelevant player evidence.
+
+## Merge guidance for independent branches
+
+Prefer new modules and narrow glue commits. Current high-conflict files include
+`server/index.ts`, `server/narrativeRepository.ts`, `src/App.tsx`, `src/main.tsx`,
+and the play entrypoint. Assign one integrator to make the final small changes in
+those files after the isolated work lands.
+
+Suggested merge order:
+
+1. S7-A schema/repository and clone support.
+2. S7-B authored content and deterministic fixtures.
+3. S7-C judge service/evaluation persistence.
+4. S7-D story/API glue.
+5. S7-E UI.
+6. S7-F acceptance hardening.
+
+Each branch should state its migration dependency and avoid renumbering an
+already-shared migration silently. If two branches need schema changes, reserve
+migration numbers before implementation or keep one branch schema-free.
+
+## Definition of done
+
+From a fresh playthrough, a player reaches Scene 7 and sees the inventor
+assignment. They paste one accepted Google Patents screenshot. One source
+document appears on their board, the server persists the asset and OCR, the
+authored match rule records an auditable evaluation, and the level obtains
+`scene7.nils_inventor_proved`. The UI clearly confirms what the evidence proved
+and offers Continue; the story then enters Scene 8. Reloading preserves the
+document and completed state, repeating the evaluation grants nothing twice,
+another player's level is unaffected, no URL was required, and
+`barricelli_luggage` has not yet been awarded.
+
+=======
+  goals: LevelGoal[]

+
+`newlyCompleted` is response-local: a reload returns complete with

+
+## Security and cost limits

+- Require identity and level ownership on player mutations.
+- Limit upload bytes, OCR/model characters, output tokens, duration, and retries.
+- Never expose reference anchors or judge instructions to play mode.
+- Treat filenames, MIME declarations, OCR, and model output as untrusted.

+# Story flow graph: the mystery editor
+
+Status: **implemented** (migrations `018`–`021`). A mystery plays as a walk of an
+authored node graph; the slot/chapter model has been retired in a clean cutover.
+Gates are stubbed and the LLM gate is not built (see *Implemented vs deferred*).
+Builds on the NPC/dialogue work in [narrative-todo.md](narrative-todo.md).
+
+## Concept
+
+A mystery is a **directed graph of nodes**. Each node has one implicit input and N
+output **terminals**; a terminal carries its single outgoing wire (`to_node_id`) —
+there is no separate edges table. A playthrough walks the graph from the mystery's
+single **entrypoint node** (`mysteries.entry_node_id`).
+
+- At the **node level** cycles are allowed (a gate can route back to a level). The
+  runtime only advances a node when the player acts, so loops never spin on their own.
+- Within a **dialogue node** the utterances form a **tree** (each utterance has one
+  parent), so back-edges/loops are not expressible there yet.
+
+## Node types
+
+| type | what it does | terminals |
+|---|---|---|
+| `cutscene` | Renders a bespoke React component chosen from a frontend registry (`component_key`), e.g. a title card. Opaque to the graph so set-pieces don't clutter the dialogue tree. | usually 1 (`continue`) |
+| `dialogue` | The standard NPC dialogue box, driven by an utterance tree (NPC lines + player choices). | 1+ (e.g. `continue`, or `proceed`/`retry` for a branch) |
+| `level` | Instantiates a playable board from a level template version and hands over to the investigation. | 1 (`report_back`) |
+| `det_gate` | Deterministic gate. **Currently a stub**: auto-follows its first terminal. Intended to inspect the previous node's output (a level's case report, a dialogue's chosen path) and route accordingly. | 1+ |
+| `llm_gate` | LLM gate — **not implemented**. Intended: read allowlisted player state, return one terminal key (constrained output). | 1+ |
+
+Gates are resolved server-side during `advance` and never surfaced to the player.
+
+## Data model
+
+Two core tables plus `utterances`; type-specific scalars are folded onto the node
+(kept honest by CHECKs) rather than in per-type subtype tables.
+
+```sql
+CREATE TABLE osint.story_nodes (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  mystery_id UUID NOT NULL REFERENCES osint.mysteries(id) ON DELETE CASCADE,
+  node_type TEXT NOT NULL CHECK (node_type IN ('cutscene','dialogue','level','det_gate','llm_gate')),
+  label TEXT NOT NULL DEFAULT '',
+  has_utterances BOOLEAN NOT NULL DEFAULT FALSE,
+  xpos DOUBLE PRECISION NOT NULL,
+  ypos DOUBLE PRECISION NOT NULL,
+  -- Folded, type-specific scalars. Nullable during authoring; "required for type"
+  -- is a publish-time concern, so only these exclusion CHECKs are enforced.
+  level_template_version_id UUID REFERENCES osint.level_template_versions(id),
+  component_key TEXT,  -- cutscene: frontend component; gate: (future) backend gate fn
+  CHECK (level_template_version_id IS NULL OR node_type = 'level'),
+  CHECK (component_key IS NULL OR node_type IN ('cutscene','det_gate','llm_gate'))
+);
+
+-- Output ports. A terminal owns its single outgoing wire; no edges table.
+CREATE TABLE osint.story_node_terminals (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  parent_node_id UUID NOT NULL REFERENCES osint.story_nodes(id) ON DELETE CASCADE,
+  terminal_key TEXT NOT NULL,
+  label TEXT NOT NULL DEFAULT '',
+  to_node_id UUID REFERENCES osint.story_nodes(id) ON DELETE SET NULL, -- NULL = unwired/end
+  sort_order INTEGER NOT NULL DEFAULT 0,
+  UNIQUE (parent_node_id, terminal_key)
+);
+-- Same-mystery integrity for to_node_id is enforced in the repository (not a
+-- DB trigger). entry_node_id is nullable so nodes can be inserted before it is set.
+ALTER TABLE osint.mysteries ADD COLUMN entry_node_id UUID REFERENCES osint.story_nodes(id) ON DELETE SET NULL;
+```
+
+### Utterances — a dialogue node's content
+
+One table for both NPC lines and player choices, distinguished by `utterer`.
+
+```sql
+CREATE TABLE osint.utterances (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  node_id UUID NOT NULL REFERENCES osint.story_nodes(id) ON DELETE CASCADE,
+  utterer TEXT NOT NULL DEFAULT 'npc' CHECK (utterer IN ('npc','player')),
+  npc_id UUID REFERENCES osint.npcs(id),   -- speaker for NPC lines; NULL for player choices
+  pose_key TEXT,                            -- resolved with the usual pose fallback
+  text TEXT NOT NULL DEFAULT '',
+  parent_utterance_id UUID REFERENCES osint.utterances(id) ON DELETE CASCADE,       -- the utterance this one follows
+  advances_to_utterance_id UUID REFERENCES osint.utterances(id) ON DELETE SET NULL, -- VESTIGIAL / unused (see below)
+  terminal_id UUID REFERENCES osint.story_node_terminals(id) ON DELETE SET NULL,    -- exit: leave the node via this terminal
+  effect TEXT,                              -- reserved side-effect hook (unused)
+  xpos DOUBLE PRECISION NOT NULL DEFAULT 0, -- position in the utterance sub-canvas
+  ypos DOUBLE PRECISION NOT NULL DEFAULT 0,
+  sort_order INTEGER NOT NULL DEFAULT 0
+);
+```
+
+**The model is parent-only with count-based meaning.** An utterance's *children*
+(the utterances whose `parent_utterance_id` points to it) are what come after it:
+
+- **0 children** + `terminal_id` set ⇒ this line **exits** the node via that terminal.
+- **1 child** ⇒ **linear** next line (rendered as a solid wire).
+- **2+ children** ⇒ **player options** (rendered as dotted wires); by convention the
+  children are `player` utterances and the parent is an NPC prompt.
+
+The root of a node's tree is the utterance with no parent. `advances_to_utterance_id`
+is a leftover column from an earlier design and is **not used**; a follow-up
+migration can drop it. Because each utterance has a single parent the graph is a
+tree — no back-edges/loops within a node yet.
+
+### Cutscene component registry (frontend)
+
+Mirrors the exhibit registry: `component_key → React component`. Each owns its
+presentation and signals completion with an optional terminal key.
+
+```ts
+type CutsceneComponent = React.FC<{ onComplete: (terminalKey?: string) => void }>
+// registry: { 'glass-harbour-diversion': GlassHarbourDiversion }
+```
+
+For a single-terminal cutscene, `onComplete()` follows the only terminal.
+
+## Editing UX
+
+The same canvas engine (pan, zoom, drag, curved wires, click-a-wire-to-delete) is
+reused at two levels.
+
+**Mystery graph** — `story_nodes` as cards, wired by `terminal.to_node_id`. Laid out
+**vertically**: the input port is on **top**, output terminals along the **bottom**,
+and flow runs downward. Double-clicking a dialogue node drills into its utterances.
+
+**Utterance crafter** — a dialogue node's utterances as draggable cards; the node's
+output terminals appear as **exit sinks** docked to the right. Each card has one
+output port:
+
+- Drag a card's port to another card ⇒ that card becomes a **child** (1 child = solid
+  linear; 2+ = dotted options).
+- Drag to an exit sink ⇒ the card leaves the node via that `terminal_id`.
+- **Tab** on a selected utterance adds a child (a lone child stays a linear NPC line;
+  a second flips them to player options). **1** / **2** set the selected card's
+  speaker. **Ctrl/Cmd+Z** undoes connection/creation edits. Cards colour by speaker
+  and auto-expand to full text.
+
+## Runtime traversal
+
+The playthrough tracks position with `current_node_id` (and `current_level_id`,
+set while on a level node); the slot fields were dropped.
+
+```sql
+ALTER TABLE osint.playthroughs ADD COLUMN current_node_id UUID REFERENCES osint.story_nodes(id) ON DELETE SET NULL;
+```
+
+- **New Game** creates a playthrough at the entrypoint (bound to the JWT identity,
+  with a dev test-user fallback).
+- **`getCurrentPlaythrough`** returns the resolved current node: a cutscene
+  (`componentKey`), a level (`levelSlug`), or a **dialogue tree** (all utterances with
+  resolved speaker/pose, ordered `childIds`, and each exit's `terminalKey`, plus the
+  `rootId`).
+- **`advance(terminalKey?)`** follows a terminal, **auto-skips gates** (the stub
+  det_gate takes its first terminal), instantiates the board when entering a level,
+  and finishes when a followed terminal has no target.
+- **Dialogue is walked on the client** (`DialoguePlayer`): play NPC lines with the
+  typewriter; at a branch (2+ player children) present choice buttons; a chosen child
+  leads to its next line or, if it has a `terminalKey`, calls `advance(terminalKey)`
+  to leave the node — routing the graph to a different next node.
+
+## Glass Harbour seed
+
+Authored in `mysteries/glass-harbor/mystery.json` (`narrative.graph`) and seeded by
+the importer, so it survives re-imports. It is linear:
+
+```
+[cutscene: glass-harbour-diversion] → [dialogue: Briefing] → [level: glass-harbor] → [dialogue: Debrief] → (end)
+```
+
+Branching (player options routing to different terminals) is supported and tested,
+just not used in the seed.
+
+## Implemented vs deferred
+
+**Implemented:** graph schema, node/terminal/utterance CRUD + admin editors, the
+runtime cutover (cutscene / dialogue-tree / level traversal, branching dialogue),
+the vertical mystery-graph canvas, the utterance crafter, and the seed.
+
+**Deferred:**
+- **Real gates.** `det_gate` is a hardcoded "first terminal" stub; `llm_gate` is
+  unbuilt. Both want the **Case Report / Claims** (Milestone 5) as input, plus a
+  gate-function registry keyed like cutscene components.
+- **Within-node loops** (an utterance's single parent makes each dialogue a tree).
+- **Drop `advances_to_utterance_id`** and the reserved `effect` column.
+- **Cutscene params** and real pose art.
+
+## Validation rules
+
+- One `entry_node_id` per mystery (soft-recommended to be a `cutscene`).
+- A terminal's `to_node_id` must share its parent node's mystery (repo-enforced).
+- An utterance's `terminal_id` must belong to its node; parent links stay in-node.
+- Unreachable nodes and unwired terminals are allowed (deliberate ends).

+# Mystery content packages
+
+Mysteries live outside the React application as authoring manifests and immutable source assets. Importing a manifest exercises the same public operations as the level editor: it creates a mutable authoring level, uploads assets, saves normalized exhibits, freezes an immutable template version, and instantiates a separate playable level.
+
+With the local Docker stack running and editing enabled:
+
+```bash
+npm run mystery:import -- mysteries/glass-harbor/mystery.json
+```
+
+The command prints the template version, authoring-level ID, playable-level ID, and player URL. Importing the same manifest again creates a new immutable version; it does not rewrite an earlier version.
+
+## The Glass Harbor Diversion
+
+This compact first mystery contains eight dated source documents in three folders, six unresolved Party concepts, and one fictional archival photograph. It intentionally starts without Party or Event exhibits: classification, dossier association, event reconstruction, working notes, and red-thread theory are the player’s work.
+
+The source image was generated with the built-in image-generation tool for this fictional case. Its final production prompt asked for a degraded 1987 harbor-security photograph of truck `H&F 14` unloading a `CALDER OPTICAL / FRAGILE` crate at Warehouse 3, with period-correct details and no real people or brands.
